The reality TV star and makeup guru made it to Forbes' annual ranking of the world's richest people.
Her make-up company, Kylie Cosmetics which she founded in 2015 is now worth $990 million, with Jenner owning 100% stake.
At this age, Kylie has also become the youngest self-made billionaire ever. What's interesting is that she has achieved this feat at a younger age than even Facebook founder Mark Zuckerberg who reached the ten-figure mark when he was 23.
